wow, just realized if an average person poops a pound a day, that is about 340 tons of poop dumped in the ocean for that one 274-night cruise (hopefully there's a good way to dispose of it). talk about toxic waste!
long cruises like that scare me... mostly because of this.
I would probably just opt for going to the places in the world I like to visit (thru planes first), then maybe charter a nice yacht (with hunky deck crews) for a couple days to enjoy scenes that might actually be nice to see - like Tahiti...definitely a combo of land and water - too much of one thing, I think is just not my vibe.
